CONTROLS:
GAIN:
The
gain
control is used to "make up" for the gain loss, which takes place
when the unit is compressing. It is placed after the gain-reduction circuit and
therefore has no influence on the threshold setting. The
gain
-control is
continuously variable from off to +30 dB.
RATIO:
The
ratio
control varies the ratio by which the input signal is compressed.
If the ratio selected is to 2:1, and the input signal increases 10 dB, the output
signal is only increased by 5 db. The
ratio
control is continuously variable
from 2:1 to 10:1.
THRESHOLD:
The threshold is the point where the compressor begins its action. It is
defined as the point where the gain is reduced by 1 dB.
The threshold is continuously variable from +20dBU to -40 dBU.
METER:
The VU-meter switch has three positions:
1.
Input
The meter is reading the level at the input socket.
2.
Compression
The VU-meter is reading gain reduction.
Its rest position is "0 VU", and the amount of
compression is shown as a decreasing deflection in dB.
3.
Output
The VU-meter is reading the level at the output socket.
"0 VU" is equivalent to +4 dBU.
NB:
Leave the meter switch in position
compression
as it might introduce
distortion if left in the
input
or
output
position.
IN/OUT:
This leverswitch switches the compressor in and out of the signal path. The
out position bypasses the entire compressor.
ATTACK:
The
attack
control chooses how fast/slow the compressor responds to an
increase in the input signal.
The attack control is continuously variable from 0.5 to 300 milliseconds.
RELEASE:
The
release
control chooses how fast/slow the compressor responds to a
decrease in the input signal.
The release control is continuously variable from 0,05 to 10 seconds.
